Safety rules

Pay attention to this symbol

This warning symbol points out important messages con-

cerning your safety.

Carefully read the following safety regulations and ob-

serve advised precautions in order to avoid potential haz-

ards and safeguard your health and safety.

In this manual the symbol is accompanied by the following

key-words:

WARNING: Warnings concerning unsuitable repair oper-

ations that may jeopardise the safety of Repair personnel.

DANGER: Specific warnings concerning potential haz-

ANIL15TR0707AA

ards for operator safety or for other persons directly or

indirectly involved.

To prevent accidents

Most accidents or injuries that occur in workshops are the result of non-observance of simple and fundamental safety

regulations. For this reason, IN MOST CASES THESE ACCIDENTS CAN BE AVOIDED by foreseeing possible

causes and consequently acting with the necessary caution and care.

Accidents may occur with all types of vehicle, regardless of how well it was designed and built.

A careful and judicious service technician is the best guarantee against accidents.

Precise observance of the most basic safety rule is normally sufficient to avoid many serious accidents.

DANGER: Never carry out any cleaning, lubrication or maintenance operations when the engine is running.

Safety rules

General guidelines:

• Carefully follow specified repair and maintenance procedures.

• Do not wear rings, wristwatches, jewels, unbuttoned or flapping clothing such as ties, torn clothes, scarves, open

jackets or shirts with open zips which could get caught on moving parts.

Use approved safety clothing such as anti-slipping footwear, gloves, safety goggles, helmets, etc.

• Do not carry out repair operations with someone sitting in the driver’s seat, unless the person is a trained technician

who is assisting with the operation in question.

• Do not operate the vehicle or use any of the implements from different positions, other than the driver’s seat.

• Do not carry out operations on the vehicle with the engine running, unless specifically indicated.

• Stop the engine and ensure that all pressure is relieved from hydraulic circuits before removing caps, covers, valves,

etc.

• All repair and maintenance operations must be carried out using extreme care and attention.

• Service steps and platforms used in a workshop or in the field should be built in compliance with the safety rules in

force.

• Disconnect the batteries and label all controls to indicate that the vehicle is being serviced. Block the machine and

all equipment which should be raised.

• Do not check or fill fuel tanks, accumulator batteries, nor use starting liquid when smoking or near naked flames,

as these fluids are inflammable.

• Brakes are inoperative when manually released for repair or maintenance purposes. Use blocks or similar devices

to control the machine in these conditions.

51553302 19/11/2018

INTRODUCTION

•

The fuel nozzle should always be in contact with the filling aperture: Maintain this contact until the fuel stops flowing

into the tank to avoid possible sparks due to static electricity buildup.

•

Only use specified towing points for towing the vehicle. Connect parts carefully. Make sure that all pins and/or

locks are secured in position before applying traction. Never remain near the towing bars, cables or chains that are

operating under load.

•

Transport vehicles that cannot be driven using a trailer or a low-loading platform trolley, if available.

•

When loading or unloading the vehicle from the trailer (or other means of transport), select a flat area capable of

sustaining the trailer or truck wheels. Firmly secure the vehicle to the truck or trailer and lock the wheels in the

position used by the carrier.

•

Electric heaters, battery-chargers and similar equipment must only be powered by auxiliary power supplies with

efficient ground insulation to avoid electrical shock hazards.

•

Always use suitable hoisting or lifting devices when raising or moving heavy parts.

•

Take extra care if bystanders are present.

•

Never pour petrol or diesel oil into open, wide or low containers.

•

Never use gasoline, diesel oil or other inflammable liquids as cleaning agents. Use non-inflammable, non-toxic

commercially available solvents.

•

Wear safety goggles with side guards when cleaning parts with compressed air.

•

Limit the air pressure to a maximum of 2.1 bar, according to local regulations.

•

Do not run the engine in confined spaces without suitable ventilation.

•

Do not smoke, use naked flames, or cause sparks in the area when fuel filling or handling highly inflammable liquids.

•

All movements must be carried out carefully when working under, on or near the vehicle. Wear suitable safety

clothing, i.e., hard hat, safety goggles and special shoes.

•

When carrying out checks with the engine running, request the assistance of an operator in the driver’s seat. The

operator must maintain visual contact with the service technician at all times.

•

If operating outside the workshop, position the vehicle on a flat surface and lock in position. If working on a slope,

lock the vehicle in position. Move to a flat area as soon as is safely possible.

•

If operating outside the workshop, position the vehicle on a flat surface and lock in position. If working on a slope,

lock the vehicle in position.

Move to a flat area as soon as is safely possible.

•

Damaged or bent chains or cables are unreliable. Do not use them for lifting or towing. Always use suitable pro-

tective gloves when handling chains or cables.

•

Chains should always be safely secured. Make sure that the hitch-up point is capable of sustaining the load in

question. Keep the area near the hitch-up point, chains or cables free of all bystanders.

•

Maintenance and repair operations must be carried out in a CLEAN and DRY area. Eliminate any water or oil

spillage immediately.

•

Do not create piles of oil or grease-soaked rags as they represent a serious fire hazard. Always place them into a

metal container.

Before starting the tractor or its attachments, check, adjust and block the operator’s seat. Also check that there are

no persons within the vehicle or implement range of action.

•

Empty pockets of all objects that may fall unobserved into the vehicle parts.

•

In the presence of protruding metal parts, use protective goggles or goggles with side guards, helmets, special

footwear and gloves.

•

When welding, use protective safety devices: tinted safety goggles, helmets, special overalls, gloves and footwear.

All persons present in the area where welding is taking place must wear tinted goggles. NEVER LOOK DIRECTLY

AT THE WELDING ARC WITHOUT SUITABLE EYE PROTECTION.

•

Metal cables tend to fray with repeated use. Always use suitable protective devices (gloves, goggles, etc.) when

handling cables.

•

Handle all parts with great care. Do not put your hands or fingers between moving parts. Always wear suitable

safety clothing-safety goggles, gloves and shoes.

INTRODUCTION

Starting

• Never run the engine in confined spaces that are not equipped with adequate ventilation for exhaust gas extraction.

• Never place the head, body, limbs, feet, hands or fingers near fans or rotating belts.

Engine

• Always loosen the radiator cap slowly before removing it to allow any remaining pressure in the system to be dis-

charged. Filling up with coolant should only be carried out with theengine stopped or idling (if hot).

• Never fill up with fuel when the engine is running, especially if hot, in order to prevent the outbreak of fire as a result

of fuel spillage.

• Never check or adjust fan belt tension when the engine is running.

Never adjust the fuel injection pump when the vehicle is moving.

• Never lubricate the vehicle when the engine is running.

Electrical systems

• If it is necessary to use auxiliary batteries, remember that both ends of the cables must be connected as follows:

(+) with (+) and (-) with(-).

Avoid short-circuiting the terminals. GAS RELEASED FROM BATTERIES IS HIGHLY INFLAMMABLE. During

charging, leave the battery compartment uncovered to improve ventilation. Never check the battery charge using

“jumpers” (metal objects placed on the terminals). Avoid sparks or flames near the battery zone. Do no smoke to

prevent explosion hazards.

• Before servicing operations, check for fuel or current leaks. Eliminate any eventual leaks before proceeding with

work.

• Never charge batteries in confined spaces. Make sure that there is adequate ventilation in order to prevent acci-

dental explosion hazards as a result of the accumulation of gases released during charging operations.

• Always disconnect the batteries before performing any kind of servicing on the electrical system.

Hydraulic systems

• A liquid leaking from a tiny hole may be almost invisible but, at the same time, be powerful enough to penetrate the

skin. Therefore, use a piece of cardboard or wood for this purpose. NEVER DO IT WITH YOUR HANDS: If any

liquid penetrates skin tissue, call for medical aid immediately. Failure to treat this condition with correct medical

procedure may result in serious infection or dermatosis.

• In order to check the pressure in the system use suitable instruments.

Wheels and tyres

• Make sure that the tyres are correctly inflated at the pressure specified by the manufacturer. Periodically check

possible damages to the rims and tyres.

• Stand away from (at the side of) the tyre when checking inflation pressure.

• Only check pressure when the vehicle is unloaded and the tyres are cold, to avoid incorrect readings as a result of

over-pressure.

Do not reuse parts of recovered wheels as improper welding, brazing or heating may weaken the wheel and make

it fail.

• Never cut or weld a rim mounted with an inflated tyre.

• To remove the wheels, lock both the front and rear vehicle wheels. After having raised the vehicle, position supports

underneath, according to regulations in force.

• Deflate the tyre before removing any object caught in the tyre tread.

• Never inflate tyres using inflammable gases, as this may result in explosions and injury to by standards.

51553302 19/11/2018

INTRODUCTION

Removal and re-fitting

• Lift and handle all heavy parts using suitable hoisting equipment. Make sure that parts are sustained by appropriate

hooks and slings. Use the hoisting eyebolts for lifting operations. Extra care should be taken if persons are present

near the load to be lifted.

• Handle all parts with carefully. Do not put your hands or fingers between parts. Wear suitable safety clothing, i.e.

safety goggles, gloves and footwear.

• Avoid twisting chains or metal cables. Always wear safety gloves when handling cables or chains.

INTRODUCTION

Basic instructions

Important notice

All maintenance and repair work described in this manual must be performed exclusively by NEW HOLLAND service

technicians, in strict accordance with the instructions given and using any specific tools necessary.

Anyone performing the operations described herein without strictly following the instructions is personally responsible

for any eventual injury or damage to property.

Battery

Before carrying out any kind of service operation disconnect and isolate the battery negative lead, unless otherwise

requested for specific operations (e.g.: operations requiring the engine to be running), after which it is necessary to

disconnect the above mentioned lead to complete the work.

Shimming

For each adjustment operation, select adjusting shims and measure individually using a micrometer, then add up

the recorded values. Do not rely on measuring the entire shimming set, which may be incorrect, or the rated value

indicated for each shim.

Rotating shaft seals

For correct rotating shaft seal installation, proceed as follows:

• Before assembly, allow the seal to soak in the oil it will be sealing for at least thirty minutes.

• Thoroughly clean the shaft and check that the working surface on the shaft is not damaged.

• Position the sealing lip facing the fluid; with hydrodynamic lips, take into consideration the shaft rotation direction

and position the grooves so that they will deviate the fluid towards the inner side of the seal.

• Smear the sealing lip with a thin layer of lubricant (use oil rather than grease) and fill the gap between the sealing

lip and the dust lip on double lip seals with grease.

• Insert the seal in its seat and press down using a flat punch, do not tap the seal with a hammer or mallet.

• Whilst inserting the seal, check that the it is perpendicular to the seat; once settled, make sure that it makes contact

with the thrust element, if required.

• To prevent damaging the seal lip on the shaft, position a protective guard during installation operations.

O-ring seals

Lubricate the O-ring seals before inserting them in the seats, this will prevent them from overturning and twisting,

which would jeopardise sealing efficiency.

Sealing compounds

Apply one of the following sealing compounds on the mating surfaces marked with an X: LOCTITE® 518™ or LOCTITE®

5205 or SUPERBOND 559 or BETALOK A272M.

Before applying the sealing compound, prepare the surfaces as follows:

• Remove any incrustations using a wire brush.

• Thoroughly decrease the surfaces using one of the following cleaning agent: trichlorethylene, petrol or water and

soda solution.

Bearings

When installing bearings it is advised to:

• Heat the bearings to 80 - 90 °C (176 - 194 °F) before fitting on the shafts.

• Allow the bearings to cool before installing them from the outside.

51553302 19/11/2018

INTRODUCTION

Spring pins

When fitting split socket elastic pins, ensure that the pin notch is positioned in the direction of the force required to

stress the pin.

Spiral spring pins do not require special positioning.

Spare parts

Use genuine parts only.

Only genuine spare parts guarantee the same quality, duration and safety as they are the same parts that are assem-

bled during production.

Only genuine parts can offer this guarantee.

When ordering spare parts, always provide the following information:

• Tractor model (commercial name) and frame number.

• Engine type and number.

• Part number of the ordered part, which can be found on the “Spare Parts Catalogue”, which is the base for order

processing.

Notes for equipment

The tools that NEW HOLLAND offer and illustrate in this manual are:

• Specifically researched and designed for use with NEW HOLLAND vehicles.

• Necessary to make a reliable repair.

• Accurately built and strictly tested to offer efficient and long-lasting working means.

By using these tools, repair personnel will benefit from:

• Operating in optimal technical conditions.

• Obtaining the best results.

• Save time and effort.

• Working in safe conditions.

Important notes

Wear limit values indicated for certain parts are recommended, but not binding. The terms “front”, “rear”, “right-hand”

and “left-hand” (when referred to different parts) are intended as seen from the driving position with the tractor in the

normal direction of movement.

Moving the tractor with the battery removed

External power supply cables should only be connected to the respective positive and negative cable terminals, using

efficient clamps that guarantee adequate and secure contact.

Disconnect all services (lights, windshield wipers, etc.) before starting the vehicle.

If the tractor electrical system requires checking, carry out operations with the power supply connected. Once check-

ing is completed, disconnect all services and switch off the power supply before disconnecting the cables.
